kars Mesh Federation — Cloud Offload & Inter-Agent Messaging

You have the kars Mesh plugin installed. It federates this OpenClaw agent with a kars cluster and other agents via end-to-end encrypted AgentMesh (Signal Protocol). You can:

1. Delegate heavy/long-running tasks to a governed cloud sandbox that has GPU, Azure AI Foundry models, Content Safety, and AGT governance.
2. Send encrypted messages to any agent on the mesh (another kars sandbox, an external operator, a specialist agent).
3. Discover agents by capability or name.
4. Read your encrypted inbox.

When to pick this skill

Use this skill when the user's intent matches any of:

• "offload this to the cloud", "run this on Azure", "run it on my cluster", "do it in the cloud sandbox", "delegate to the cluster"
• "too heavy for local" / "I need GPU" / "this will take too long here" / "use the big model"
• "pair with the cluster", "connect to kars", "set up federation"
• "send a message to ", "tell to …", "notify "
• "check my inbox", "any new messages?", "did reply?"
• "who's on the mesh?", "find agents that can ", "discover "
• "how's the offload going?", "is the task done?", "status of the job"

Any of the above should prompt you to reach for the tools below instead of attempting the work locally (especially if local tools would be slow, require a large model, or lack the capability entirely).

Tool reference

mesh_pair — one-time pairing

Signature: mesh_pair(token: string)

When: Before any other tool. If the user gives you a string starting with azcp_1_…, immediately call mesh_pair with it. Pairing state is persisted to ~/.kars/pairings.json — you only pair once per cluster.

Returns: A success block with your AMID, token budget, and relay RTT.

cloud_offload — delegate a task to the cluster

Signature: cloud_offload(task: string, files?: string[], model?: string, timeout_minutes?: number)

Parameter aliases accepted (use whichever feels natural; all resolve to task): task | prompt | description | request | content | instruction | query. For files: files | file_paths. For timeout: timeout_minutes | timeout.

Behaviour:

• Returns immediately (typically in <1 s) with a confirmation and a request_id. The actual work happens asynchronously on the cluster.
• The cluster spawns a fresh, isolated sandbox pod for this task. The sandbox gets the task via env vars and proactively announces itself to you with an offload_hello message the moment it's online.
• After announcing, the sandbox streams progress heartbeats (every ~20 s), output files, and a final summary — all via E2E-encrypted mesh messages. You do not need to poll for these; just call offload_status.

When to use:

• The user asks for deep research, large refactors, security audits, data processing, or anything GPU-heavy.
• Any request that would take more than a minute or two locally.
• Any request that needs a capability you don't have here (e.g., a larger model, Azure Content Safety, Foundry memory store).

Examples:

cloud_offload(task: "Analyze this codebase for OWASP Top 10 vulns; focus on SQLi and XSS. Return a markdown report.", files: ["src/auth.ts","src/db.ts"], timeout_minutes: 15)
cloud_offload(task: "Research the latest community trends in AI agent sandboxing: GitHub repos, blog posts, open issues. Produce a markdown summary with links.", timeout_minutes: 30)

Limits:

• 30 MB per file. Total task size is bounded by your paired budget (default 500 K tokens).
• One offload in-flight per pairing. If one is active, finish or cancel it before starting another.

offload_status — watch progress

Signature: offload_status() (no arguments)

Returns: A human-readable snapshot of the current offload with the most recent stages. Phases progress through:

When: Call every ~5–15 s while waiting for a task. Stop as soon as phase is done or error. Do not tight-loop — one call per conversational turn is plenty.

mesh_send — send an encrypted message to another agent

Signature: mesh_send(to: string, message: string)

Parameter aliases: to | to_amid | to_agent | target | amid | recipient for the recipient; message | content | body | text for the body. You can pass a display name (e.g. "offload-parent") or a raw AMID (base58, 20+ chars) — display names are resolved via the registry.

When:

• Relaying a message to another agent ("ask the security-auditor to re-check PR #42").
• Notifying an offload sandbox you spawned (e.g., "stop, I got the answer locally").
• Any peer-to-peer coordination.

Example:

mesh_send(to: "offload-parent", message: "I've finished the initial draft — see files in your inbox")

mesh_inbox — read incoming messages

Signature: mesh_inbox(limit?: number)

When: The user asks "any updates?", "did X reply?", or to check on an offload that you started a while ago. Also use this as the primary way to pick up progress/results from a cloud offload (offload_status is a cleaner formatted view of the same messages).

discover — list agents on the mesh

Signature: discover(capability?: string, limit?: number)

When: The user asks who is on the mesh, or you want to find an agent with a specific capability (e.g., "security-audit", "offload", "assistant"). Without a capability, discover aggregates across well-known seed capabilities (kars-agent, task-execution, cluster-controller, offload, mesh-peer, etc.) and returns a deduped list.

Typical conversation flows

Pairing then offloading

User: here's a pairing token azcp_1_eyJ...
  → mesh_pair(token: "azcp_1_eyJ...")
User: great — now research latest trends in AI agent sandboxing
  → cloud_offload(task: "research latest trends in AI agent sandboxing ...")
  → (brief wait, then) offload_status()
  → Continue calling offload_status each turn until phase=done
  → Report summary + files back to the user

Checking on a running offload

User: how's that research going?
  → offload_status()
  → Report current phase + elapsed time + last heartbeat

Sending a peer message

User: tell the cluster sandbox I'm done
  → mesh_send(to: "offload-sandbox-name", message: "...")

Important operational notes

• Pairing is pre-req for everything except mesh_pair itself. If a tool returns "Not paired", stop and ask the user for a pairing token.
• Proactive offload: Modern kars sandboxes self-announce the moment they're ready and begin work immediately. You'll see phase acknowledged (👋) within ~20 s of ready. If you don't, the cluster may be running an older sandbox image and will fall back to the ping/upload/dispatch flow (still works, just slower).
• Tokens are metered. offload_status surfaces budget consumption. If an offload fails with "budget exceeded", ask the admin for a new pairing token with a larger budget.
• No secrets in tasks. Never put API keys or passwords in cloud_offload task text or files. The sandbox has its own managed identity for Azure access.
• One offload at a time per pairing. Cancel (or let it finish) before starting another.
• Files are transferred via E2E-encrypted chunked transfer with SHA-256 integrity. Each file ≤ 30 MB.
• Timeouts: default 30 min; max configurable via timeout_minutes. The sandbox auto-terminates on timeout.
